APPARATUS FOR HEATING AND PURIFYING WATER.

SPECIFICATION forming, part of Letters Patent No. 407,819, dated July 30, 1889.

Application filed January 2, 1885. Serial No. 151,762- (No model.)

To all whom, it 'ntay 007000772..-

Be it known that I, ALLEN P. CREQUE, of the city, county, and State of New York, have invented an Improvement in Apparatus for Heating and Purifying ater, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representinglike parts.

My invention, relating to apparatus for heating, purifying, and circulating water, consists in various details of construction and arrangement .of parts, as will be hereinafter described, and specifically pointed outin the claims at the end of this specification.

Figure 1 is a vertical section of an apparatus for heating and purifying water embodying this invention, the multipassagecover and its tubular projections and connected pipes and tubingbeing shown in elevation; Fig. 2, an enlarged longitudinal section of the Water-inlet pipe and valve controlling the same; Fig. 3, a vertical section of the compound coupling or multipassage cover and its tubular projections, the nipple or bushing to which the multipassage cover is attached by the coupling-nut and part of the boiler-bottom being shown; Fig. 4, a plan view of the said cover, and Fig. 5 a section of Fig. 1 on line :0 00 to more clearly illustrate the arrangement of pipes Within the boiler.

The shell of the boiler or reservoir a may be of any suitable or usual size, shape, and material, its bottom plate b being provided with an opening 0 of a size sufficient for the passage of all the pipes entering the lower part of the reservoir and also to readily admit a mans hand. The said opening a is covered by a multipassage cover (I, (see Figs. 3 and 4,) provided with a series of openings for the different pipes at the lower end of the reservoir, the said cover preferably having cast as integral parts of it, or having otherwise tightly connected with it, short tubular projections (Z (1 (1 which may be straight or curved in any desired direction, and to which projections the pipes or tubing, both within and outside of the reservoir, may be connected by suitable joints. \Vhen a pipe is to be extended upward from one of the said tubular projections into the interior of the reservoir, the said projection may be threaded at its upper end or head, as represented at 1), to enable the said internal pipe to be secured to it.

The cover cl, which I shall designate as the multipassage cover, may be clampedto or be disconnected from the bottom plate I) of the reservoir without rotation of the said plate and consequent change in relative position of the connecting pieces and pipes joined therewith. As shown in Fig. 3, the plate (1 is adapted to be fastened to the bottom plate I) by a clamping device shown as a cou.plingnut e, screwed onto a flanged and threaded nipple or bushing f, which in Fig. 3 is shown as inserted through a hole in the bottom plate I) of the boiler.

The nipple or bushing may be soldered to the bot-tom plate Z) if the said plate is of copper, or it may constitute an integral portion of the said bottom plate if the said plate is composed of iron or steel, or the said nipple f may be screwed into a screw-threaded hole in the bottom plate and the coupling-nut be then screwed upon it. To apply the multipassage cover after the leaden or other external connecting-pipes have been attached to the tubular projection below the said cover, the boiler is held a short distance above the said cover, leaving sufficient space between it and the hand-hole to enable the tubes which are to enter the boiler to be placed therein and screwed or attached by hand to the upper side of the multipassage cover, and, such connection having been completed, the boiler will be lowered and the clamping nut or screw device will be rotated to effect the clamping of the said plate in position. v

The multipassage cover will be preferably cast integral with one or more tubular projections when the said projections are shaped or placed in such direction that the clamping nut or ring 6 may be easily slipped over them; but when two or more of the said tubular proj ections radiate in opposite or widely different directions, so that the-said clamping nut or ring cannot be slipped or passed over them,

then in this case one or more of the tubular projections are inserted from above through an orifice provided in the multipassage cover for the said projection and through the clamping nut or ring previously passed over the other projections integral with the clampingplate until the head on the inner end of the projection shall be seated upon the upper side of the said multipassage cover, these latter projections being then soldered or otherwise secured to the said multipassage cover. The cold-water-supply pipe y will be connected with the tubular projection cl outside the cover 01, and above the said cover the pipe will be continued by an extension or metal pipe 9, which will be extended up into the reservoir for some distance. provided with a check-valve 7L, (shown in Fig. 2 as seated on the end of the said pipe,) the said valve 7t being provided with guides h, which slide upon the outside of the pipe 9 and have their movement limited by stops 71, connected therewith. The function of the valve 71 will be hereinafter described.

The coldwater is conveyed from the reservoir a to the lower portion of the heat-er (indicated at 2') through circulating-pipes 70 R the one marked 70 having, as herein shown, a lateral opening or mouth located above the bottom plate I) and above the sediment-line. The pipe 70 is connected with the tubular projection d of the plate d, and the water, passing out through the said tubular projection,

enters the heater 2' through the pipe 70 and from the heater the hot water is returned to the reservoir through a circulating-pipe m, the tubular projection d, and extension hotwater-inlet pipe m, the latter discharging the ,heated water at the top of the reservoir, both the said circulating-pipes being shown in this instance as passing through the opening in the bottom of the reservoir. 7 l

The cold water in accordance with natural laws collects in the lower end of the reservoir a, from which it passes through the pipes Z0 k into the heater 11, where it becomes heated, expands, and then rises and passes through the pipes on m into the upper end of the reservoir, where it will remain on top of the colder water below. The circulation thus effected will continue in well-known manner until the entire contents of the reservoir a becomes heated down to the level of the inlet of the pipe k.

The sedimentary matter in the reservoir will accumulate on and in the concaved portion of the bottom plate 1); but as the discharge-orifice of the cold-water-inlet pipe 9 and the inlet-mouth of the pipe kare both located above the said bottom plate the water will be admitted to the reservoir, and its circulation will go on without disturbing the sedimentary matter which collects in the bottom of the reservoir, and thus practically clean and pure hot water may be collected in the upper portion.of the reservoir.

The hot water is drawn for use from the reservoir either through a pipe 12, passing through the top plate of the reservoir, or through a pipe n m the former leading from .the upper end of the reservoir down through The inlet-pipe g is.

In the normal operation, when a faucet in connection with either of the pipes 02 or n is openedfthe hot water will be removed from the top of the reservoir, the cold water entering through the pipe g under a pressure sufficient to enter the reservoir and force out from it the hot water already therein. If, however, the pressure should be rem oved from the pipe g, either by cutting off the supply or by breaking the said pipe, the water would usually escape from the reservoir a through the cold-water-inlet pipe g and pipe g as soon as a faucet should be opened in either of the pipes n or n admitting air to the upper portion of the reservoir. Such discharge of the contents of the reservoir is herein obviated by means of the check-valve h, which closes whenthe pressure is less in said pipe g than above it, thus preventing the outflow of water from the reservoir through the said pipes g. If, however, the pipe 9 were closed tightly, the expansion of the water in the reservoir or the generation of steam might strain or burst thesaid reservoir, and in order to prevent such accident a small vent'or reliefpassage r is provided, it being shown inthis instance as a small notch in the valve'seat (see Fig. 2) at the end of the pipe g, which passage affords sufficient relief to prevent unduestrain on the reservoir.

' If the pipe at or n were left open fora con-,

siderable length of time, the contents of the reservoir might slowly discharge through the vent r, and in order to prevent the reservoir from becoming wholly emptied the pipe g is extended upward for any desired distance into the reservoir, thus establishing a point below which water will never be withdrawn or emptied from the reservoir through said pipe.

The valve h is made tapering, as shown, so that the water issuing therefrom is thrown laterally into the reservoir instead of entering the reservoir in a compact column or jet. The multipassage cover, it will be seen, is clamped in the hand-hole, and thus obviates the necessity of rotating the said plate to effect its operative connection with or disconnection from the reservoir.

The sediment accumulating at the bottom of the reservoir may be drawn off through the sediment-pipe 3, attached to the tubular projection d Instead of making the venthole 4 in the pipe, the valve itself might be provided with a small vent-hole, as shown at 7".

It will be noticed that some of the tubular projections of the cover cZ-viz., those marked d and d are curved outwardly from the bot-tom of the plate, thus leaving the ends of the said projection, in such position as to,

upper end and inserted through an opening in the said plate from its upper side, the proj eotion (1 being brazed or soldered to the said plate to accommodate the pipe n By making the mouth of the circulatingpipe 70 in the side rather than at the end of the said pipe the sedimentary matter, in settling to the bottomof the reservoir, will not enter the said circulating-pipe, so that the hot water delivered from the circulating-pipes into the upper end of the reservoir is entirely free from sedimentary matter.

I have herein shown, as I prefer, the hot water from the heater as introduced through a tubular projection of the plate d; butI desire it to be understood that the hot water may be conducted from the heater to the reservoir by means of a pipe external to the reservoir, as in my patent, No. 290,667, to which reference may be had. The multipassage cover, having two or more tubular projections, may be used to great advantage at the top or upper end of the reservoir, as well as at the bottom.

By the term multipassage cover I desire to include a fiat or hub-like piece adapted to cover the hand-hole, the said piece having two or more tubular projections.

I claim 1. The reservoir and cold-water-inlet pipe therefor extending up through the lower end thereof, combinedwith an automatically-operated valve seating on the end of the said pipe, the said valve being automatically operated by changes of pressure upon it, substantially as described.

4. The combination, with a reservoir provided with a hand-hole, of a removable multipassage cover having two or more independent tubular projections attached to or forming part of said cover and to which the pipes or tubes can be attached, and a clamping mechanism to secure and hold the said cover in position to cap the hand-hole without rotating the removable cover, substantially as described,

5. The combination, with the water-heater of a range or stove, of a reservoir and a pipe connecting the said heater and reservoir and extended up within the said reservoir above the sediment-line, the said pipe forming the induction-pipe of the said heater and receiving water from the boiler only, substantially as described. I

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
